Abstract

L'invention concerne une plate-forme de pales refroidie passivement (16) pour rotor de turbine à gaz. Cette plate-forme (16), qui est conçue pour tourner autour d'un axe à l'intérieur d'un fluide de refroidissement stationnaire, présente une surface extérieure radiale délimitant un circuit d'écoulement gazeux annulaire; une surface intérieure radiale communiquant librement avec le fluide de refroidissement; un bord avant (17); et un bord arrière (18) comportant au moins un canal de circulation du fluide de refroidissement (23, 24, 25) dans la surface intérieure. Chaque canal comprend un circuit d'écoulement ayant comme point de départ une entrée du canal (26, 27, 28) et comme point d'arrivée une sortie du canal (29, 30, 31) et présente un élément tangentiel opposé au sens de rotation, au niveau de l'entrée du canal (26, 27, 28), et un élément axial au niveau de la sortie du canal (29, 30, 31). Les canaux de circulation du fluide sont délimités par des nervures (19, 20) ou des socles (22) qui s'étendent radialement vers l'intérieur, à partir de la surface intérieure de la plate-forme, pour diriger le débit de fluide de refroidissement et créer une turbulence. Les nervures (19, 20) renforcent la structure de la plate-forme (16) et, lorsqu'elles sont associées aux socles (22), servent à dissiper la chaleur de la plate-forme (16) une fois exposées au débit de fluide de refroidissement.
